Cpt Saki, the Whispering Soul

When Cpt Saki, the Whispering Soul enters the battlefield, search your library for any number of artifact cards with a total converted mana cost of 6 or less and put them onto the battlefield. Then shuffle your library. Put the top card of your library into your graveyard for each permanent that entered the battlefield this way.
